Specification of Letters Patent.

Patented May 22, 190e.

T0 all tui/1,0m t 'may concern:

Beit known that we, GEORGE W. Goss and CHARLES. E. Goss, citizens of theUnited States, residing at Baltimore, in the county of Fairfield andState of Ohio, have invented a new and useful Cultivator, of which thefollowing is a speciiication.

This invention relates to riding-cultivators; and among the objects ofthe invention are to simplify and generally to improve the constructionand operation of this class of devices.

Vith these and other ends in view, which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of parts,which will be hereinafter fully described, and particularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that the right is reserved to any changes, alterations, andmodiiications to which recourse may be had within the scope oftheinvention and without departing from the spirit or sacrificing theefliciency of the same.

In said drawings, Figure 1 is a perspective front view of a cultivatorconstructed in accordance with the principles of the invention. Fig. 2is a detail view, enlarged, in sectional elevation. Fig. 3 is a detailrear elevation. Fig. 4 is a detail plan view. Fig. 5 is a detail View ofthe axle-adjusting means. Fig. 6 is a detail view of the gang-supportingmeans. Fig. 7 is a perspective detail view ofthe footlever frame and thehandle-crank connected therewith. Fig. 8 is a sectional detail view ofone ofthe gang supporting wheels or rollers.

Corresponding parts in the several figures are indicated throughout'bysimilar characters of reference.

The frame of the improved cultivator includes a rear member 1, whichpreferably consists of a bar of channel-iron or steel of suitabledimensions. The side members of the frame have been shown as beingcomposed each of an upper and a lower bar 2 2, the rear ends of whichare connected with the ends of the rear member 1, as by means ofvertical bolts 3. The front of the frame is j tion.

likewise composed of an upper bar 4 and a lower bar 4, here shown asangle-bars, land the ends of which are connected with the front ends ofthe side bars 2 2 by means of vertical bolt members 5, spacing tubes orsleeves 6 being mounted upon the said bolts for the purpose of properlyspacing the upper and lower frame members. The side members 2 and 2 areconnected intermediate their ends by bolt members 7 and spacingsleeves8. The bolts 7 also serve to connect the sides of the frame withcross-bars 9 and 10, the former of which is supported upon the upper endmembers 2 2 and is constructed of round, preferably tubular, iron, whilethe cross-bar 10, which has been shown as a flat strap, is supportedupon the lower end members 2 beneath the spacing-sleeves 8. A verysimple and durable, approximately rectangular, frame is thusconstructed, which is specially adapted to contain the gangs andoperating mechanism which is to be hereinafter described.

Upon the front side of the rear or main.

frame member 1 near the ends of said frame member are provided bearings11 and 11, in which are journaled a pair of stub-axles 12, one at eachend, Said axles having cranks 13, terminatin in spindles 14, upon whichthe carrying-w eels 15 are supported for rota- Upon the inner bearings11 are mounted clip members or plates 16, having depending lugs 17, eachadapted to engage one of a plurality of segmental recesses 1 8 in thestubaxles, thus providing for the lateral adjustment of the latter, sothat the gage of the machine may be regulated according to the distancethat the rows of plants which are to be operated upon are apart fromeach other. It is obvious that such adjustment may be very easilyeffected by temporarily loosening or detaching the plates 16, which lareretained in operative position by screws 18 or other suitable means.

The lower end members 2 of the frame support rack segments 19concentrically, upon which are pivoted hand-levers 20, having stops 21,whereby they may be retained in adjusted position,

Said levers are connected, by means of link-rods 22, with collars t IOOadjusted so as to adjust the ends of the carbetween the latter by means-Near the ends of the Jframe are obliquely-disswingletrees 32.

rying-frame vertically and independently of each other. In the drawin sthe lower ends of the levers 20 have been sown as being bifurcated, soas to embrace the rack-segments. This construction is preferred; but itis not essential.

The implement herein shown is adapted to to be drawn by three horseswalking abreast, and it is therefore provided with two tongues 24, therear ends of which extend between the front frame members 4 and 4/ andbetween the cross-bars 9 and 10, being secured of bolts 25.

posed braces 26, the forward ends of which are secured upon the bolts 5at the front corners of the frame, while the rear ends of said bracesare secured uponthe bolts 25. The braces 26 are reinforced by auxiliarybraces 27, the rear ends of which are secured upon the bolts 7, wherebythe upper and lower side bars 'of the frame are intermediatelyconnected. The front ends lof the braces 27 are connected with thebraces 26 by means of bolts 28, which also form fulcrums for theequalizers 29. At the upper front corners of the frame are hooks 30,upon which are suspended draft-bars A31, carrying the outer Saiddraft-bars are connected, by means of linksl 33, with vthe outer ends ofthe equalizers. The inner ends of vthe equalizers are connected, bymeans of links 34, with the arms 35 of a bifurcated member 36, carryingat its lowerend a middle swingletree 37.

The seat-supporting bar of the device has been shown as'comprising twomembers 38 and 39, here shown as'constructed of Thalfvround iron, theupper member being supported u on the rear channel-bar 1 and extendinggeneath the cross-bar 9 and the front frameebar 4, while the lowermember 39 exy tends beneath the rear channel-bar 1 and the frontiframe-bar 4', the cross-bar 10 having a central or intermediate dip edportion which extends beneath the mem er 39 to assist insupporting'thelatten Thearms of the bifurcated sWingletree-supp'o'rting member 36are pivoted'upon a bolt or pin 40, extending through the upper seat-barmember 38 near the front vend ofthe latter. Said upper seat-l bar memberis bent downwardly in rear of the channel-bar 1 and is connected withthe lower'member'39, 'with which it contacts by means including a clip41, supporting the seat 42.` j 9 Upon the upper front frame member 4 aresuitablyfsiipported,clips 43, with which are ivotallyy connectedrearwardly extending bars V44,."halving downturned rear ends 45 whichl"ei'tend through collars or bearings upon ralat'erally-slidable bar 46,which is supportedinrear of the channel-bar 1 as by means ofkeysor pins47, passing through the 4members 45. The collars or bearings,"

which are designated 48, are firmly supported upon or connected with theslide -bar 46. Upon the bars 44 are journaled wheels 49, which travelupon the upper side of the channel-bar 1. The slide-bar 46 is providedwith depending bracket members 50, in which are journaled rollers 51,bearing upon the under side of the channel-bar, which latter thus notonly serves as a guide or track for the respective wheels and rollers,but also to prevent upward or downward displacement of the slide-bar 46.

The front frame members 4 and 4 are s aced apart at various placesintermediate t e ends thereof by meansof spacing-'sleeves 52, throughwhich extend connecting-bolts 53. The sleeves 52 afford bearings forclipplates 54, which consist simply of bent plates U-shaped incross-section and having their free ends connected by bolts 55, uponwhich are mounted the front ends of the beams 56 of the individualcultivator-gangs 57, which latter are of ordinary construction, beingprovided with standards 58 and earth-engaging blades 59 of the ordinaryor any well-known or approved construction.

The laterally-slidable bar 46 is provided with bearings 60 for the outerends of rockshafts 61, the inner ends of which have bearings inrack-segments 62 and 63, which are likewise secured up on and extendedupwardly from the sliding bar 46. The rock-shafts 61 are provided attheir outer ends with cranks 63', which are connected, by means oflinkrods 64, with the outer members of the cultivator-gangs, saidmembers being rovided with plates 65, through which said ink-rodsextend, the latter being provided beneath said lates with means, such asnuts 66, to enab e them to be utilized for lifting the members of thegangs. The rock-shafts have hand-levers- 67 fixed thereupon, as by meansof set-screws 68, and provided with stops 69, adapted Ato engage therack-segments 62. Pivoted loosely u on the rock-shafts near the innerends of the atter are levers 70, having stop members 71,' engaging therack-segments 63. Saidl levers are provided with arms 72, connected bylink-rods 73 with the inner members of the `cultivator-gangs, which areprovided with plates 74 of the link-rods, which are provided with means,such as nuts 66a, to prevent their withdrawal. The' link-rods 64 and 73are provided with stops 74 between which and the gang members aredisposed coiled springs 75, exercising pressure in a downward directionand tending to hold the gangs in operative engagement with the groundwhen the device is in operation. It will be seen that by means of thelevers 67 and 70 and related parts the outer and inner members G and Grof the cultivator-gangs are capable of being independentlyv adjustedvertically.

T e laterally-slidable bar 46 is provided IIO for the passage withdownwardly-extending arms and 76, the outer ones of which, 7 5, areslidably connected with the outer members G of thecultivator-gangs,while the inner arms 76 are in like manner slidably connected with theinner members of the cultivator-gangs G. The arms 75 and 76 areconnected adjustably with the slide-bar 46 by means of clips, as 77,which will admit of said arms being suitably spaced apart, so as toregulate the distance between the cultivator-gangs andthe individualmembers thereof, thus enabling the machine to be very readily adapted tooperate upon corn or other plants planted various distances apart. Apivotal bolt 78, which extends vertically through the seatbar members 38and 39, constitutes afulcrum, upon which vis pivotally mounted alever-frame 79, having two depending members spaced apart by means of abrace 81, through which the pivotal bolt 78 extends, each of the members80 being provided at its lower end with a foot-piece or treadle 82. Theupper end of the lever-frame 79 has a rearward-extending arm 83,securely connected therewith and provided with a handle 84. The arm 83is connected, by means of a link-rod 85, with an eye 86, formed upon oneof the sleeves or vcollars 48, connected with the slide-bar 46. It willbe seen that by manipulating the hand and foot levers, which may be donesimultaneously by the operator, who is seated in a convenient positionin rear of the foot-lever, the slide-bar 46, with all its related parts,will be moved laterally in either direction, thus providing for thelateral adjustment not only of the members of the cultivator-gangs, butalso of the means whereby said gangs are manipulated or adjusted totheir various positions.

rlhe wheels 49, which travel upon the upper side of the channel-bar ofthe frame, are preferably of the construction illustrated in detail inFig. 8 of the drawings, by reference to which it will be seen that saidwheels have hubs 87, between which and the bars 44 are interposedantifriction-rollers 88, which are retained by means of washer-plates89, adj acent to the hubs, said washer-plates being retained in positionby means, such as cotterpins 90.

From the foregoing description, taken in connection with the drawingshereto anneXed, the operation and advantages of this invention will bereadily understood by those skilled in the art to which it appertains.It has been endeavored to provide a separate and thoroughly-serviceableframe of light and durable construction and well adapted to support thecultivator-gangs and the adjusting and operating mechanism for saidgangs. The ends of the gang-carrying frame are capable of independentvertical adjustment, which is desirable under many circumstances. Meansare also provided whereby not only the gangs but the individual membersof said gangs may be adjusted transversely, so as to provide for anyvariation in the distance between the rows. It will further be observedthat the inner and outer members of the gangs are capable of independentvertical adjustment, which is obviously desirable. which have beendesignated, respectively, as the inner and the outer members, mayobviously be interchanged when desired, according to the character ofthe work to be performed.
